The PERFECTOR wheel is the latest innovation from Marmoelettomeccanic. The PERFECTOR eliminates once and for all the linear lines that are common in straight polishes on CNC machines. Thanks to both the Longlife technology and the oscillating movement of the PERFECTOR, we are able to solve the problem of the lines that can be found on flat polished edges. The PERFECTOR wheel will provide a line free, and wave free polish every time on all materials, including black granites and engineered stones
